I've wanted to ditch my Peavey Delta Blues 210 for a while but what to replace it with has been an issue. The 210 is a great amp but running my digital amp sim into its tubey goodness is basically dumb (and a huge hassle in patch-tuning).
Ideally I'd like to not lug an amp around with me and go straight to the PA but the few sound guys I asked about this seemed terrified by the idea. They said they'd probably run my amp sim into a monitor and mic that just to be safe. So I guess I should still have an amp that I can control.
Looking around the bossgtcentral.com forums lead me in the direction of keyboard amplifiers like the Roland KC-350 and Behringer K3000FX. Keyboard amps of any decent power and quality are expensive (the KC-350 is $600+ here) and they get quite heavy.
Somewhere I stumbled across the Tech 21 Power Engine PW60 extension cab:
The Tech 21 Power Engine 60 is an open-backed 1x12, 60W powered extension cab designed to be used with the Trademark 60. It is not a standalone piece; however, it can be combined with any discrete bass preamp. You don't have to tweak your usual settings or presets. Just plug into the Power Engine and go. It has a level control, 3-band active tone control, 1/4" input, and balanced XLR input and output. You can daisy-chain any number of Power Engine 60s together for the really big gigs.
Regardless of what it's intended for, it's been embraced by amp sim users. The Harmony Central reviews are glowing. "Clear", "clean", "flat", "loud", all very promising. Also it only costs $380 Canadian, weighs in at a svelte 33 pounds and if I decide to go for stereo I could grab another one without too much hassle.
I've ordered one and it should be here tonight, I'm hoping I should be able to make that cash back selling the Peavey if it's all good.
